Hey Have a Huawei P10 lite and a magenta tariff. As of today, I have no more reception (mobile Internet and telephone). In addition, I can no longer connect to my Magenta LTE router, but I can still connect to the A1. Is the SIM card broken? My brother also had to take a new SIM card recently because the old one was broken. After a whopping 80 minutes of customer service, that's how it turned out. (of which 5min talk time) Therefore I ask here first.

It can also be easy that the card has slipped and is no longer entirely on the contacts. I would take out the card and reinsert it.

Already done. I also inserted the SIM card into cell phone B… Then the same problem occurs
